IMPROVEMENT IN GAs=sTovEs- Specification forming part of Letters Patent No. h4@ U55, dated March 3, 1874; applicatie-n filed September 20, 1&73.

Toall whom 'it may concern.-

Be it known that we, CHARLES WrT'rEoK and WILLIAM G. STEINMETZ, of N ew York, in the county of New York and State oi` New York, have invented a new and Improved Gas-Stove, of which the following is a speciii` cation y `In the accompanying drawing, Figure l represents a vertical section oi' our improved gasstove on the line c c of Fig. 2; Fig. 2, a horizontal section on the line .1.' Fig. l 5" and Fig. 3, a bottom view of the same.

Similar letters of reference indicate corresponding parts.

The object of our invention is to furnish for heating and cooking purposes animproved gas-stove, which is constructed in a neat and durable manner, lighted and regulated rapidly and conveniently, and operated more economically than the common coal-stoves, besides being more advantageous for various applica tions.

A in the drawing represents the base part of the gas-stove; B, the draft-passages, arranged above the same. The base A is supported by legs a, of sufticient height to admit the lighting of the burners. The shape of the stove may be square, round, oval,"or otherwise, as preferred, and the casing around the draft-passages be arranged in any suitable manner and ornamentation. The gas is introduced topipes b of the base part A by connecting them, by a rubber or other pipe, with the mainsupplypipe, in the usual mann er. A principal faucet or stop-cock regulates the admission of gas, as required. Any number of burners, e, may be used in part A; but we prefer to use, for ordinary purposes, four, which are placed vertically on the connectingpipes b, near the walls of part A. The burners usually employed for heating purposes may be used.l 'lhe burner e nearest the supply-pipe is intended to produce the main draft through the passages B, and is, therefore, allowed to burn continually with a full supply of gas, while the supply of the other burners e is regulated, according to circumstances, `by a stopcock, j', operated by a crank,f1, and connecting-rod f2, with button g, from the outside of part A, as indicated in Fig. 3. The

temperature of the room may in this manner be fully and completely controlled, avoiding `as well an oppressive degree of heat at one .adjustable in slots h oi' base A by means ot' extension-lugs h, together with washers and set-screws h2. The admission of air to the combustion-chamber D is accomplished through the peri'orations or slots t', which are arranged along the upper part of base A. The quantity of air required for the full combustion of the gas is regulated by the higher or lower position of partition C, by which the slots i are partially opened or closed. The burners e connect with t-he combustion-chamber D by pipes l, which pass through partition C, and slide easily on the burner-tubes, together with partition-plates C. Pipes Z open into metallic extensioirburners F, which extendalong the side walls of base A, and air'slots i being provided with narrow slots Z, through which the blue heating iiames of the gas are issuing. By preference, we make the extension-burner E of the main draft-burner e oi iiat diamond shape, as may be seen in Fig. 2, while the extensions E of the other burners are of prismatic shape, as indicated in Fig. l. A larger air-hole, i', is arranged in base A, for the admission of a stronger currentto the larger casing E of the main burner e. The series of draftpassages B is connected to the base A by strong supporting bars -or feet m, to which are attached the vertical rods m. The combustion-chamber D connects, at that side opposite to the main burner, by a vertical pas sage, with a horizontal one, then at the opposite side with the next vertical passage to the second horizontal passage, &c., to the chimney, as indicated in Fig. l, the draft being indicated by arrows. The vertical rods m connect and support the draft-passages B, forming the pillars of the stove. r)She horizontal passages may be advantageously used for cooking, baking, frying, warming, and drying purposes, according to their distance from the combustion-chamber.
